Nuclear Weapons

The nuclear bomb is the weapon that revolutionized the history of war.
Atomic power is power that is obtained by fusion(joining) or fission(splitting) of two atoms. This fusion or fission creates large amounts of energy which has been utilized for many different purpose, the most first and most significant use of which is the atomic bomb.

The picture above shows how nuclear power is obtained. First a neutron is fired at an atom, splitting it. This produces energy and the split atom gives out neutrons. The energy propels the neutrons towards other atoms. The chain reaction continues and a very large amount of energy builds up.

The history of the atomic bomb started with the German Nazis discovery of the splitting of an uranium atom. Many feared Hitler will create a nuclear bomb after word spread. However, Hitler persecuted Jewish scientists, many of which are extremely clever. This resulted in many scientists seeking asylum in the USA. One example is Albert Einstein. He, abandoning his belief of pacifism, urged then president Franklin Roosevelt to develop their own nuclear bomb. Roosevelt agreed and joined hands with the U.K and Canada to create the nuclear bomb.
This project was code named the Manhatten project. This race to create the first nuclear bomb was won by USA.

So far, the Japanese cities Hiroshima and Nagasaki were the only places where atomic bombs were dropped intentionally.
Throughout the years following the first nuclear bomb, nuclear technology has improved by leaps and bounds. Nuclear bombs now are 500 times more powerful than that dropped on Nagasaki.
This military development has proved to have advanced too fast and now world leaders are working one abolishing nuclear weapons.
